Rotational Coupling

Connect SimDriveline driveline shaft with Simscape mechanical rotational elements

Library

Interface Elements

Description

You use this block to connect SimDriveline™ components with mechanical rotational elements from the Simscape™ Foundation library. Dynamically, such a connection is equivalent to connecting the mechanical rotational elements along the driveshaft connected to the interface.

The Simscape environment supports a domain representing one-dimensional rotational motion. In a Simscape mechanical rotational circuit, torque flows through a connection line, while angular velocity is defined across nodes connected by connection lines. The Rotational Coupling block rigidly couples a SimDriveline driveshaft to a Simscape mechanical rotational degree of freedom. By itself, this interface adds or removes no degrees of freedom to or from the combined driveline-circuit. Rotational Coupling preserves torque through and motion across the block, conserving mechanical power.

  • The driveline port acts, on the SimDriveline side, like a torque actuator, feeding torque from the circuit into the driveline, while maintaining the angular velocity across the block.

  • The physical conserving port acts, on the Simscape side, like a motion actuator, feeding a prescribed motion from the driveline into the circuit, while preserving the flow of torque through the block.

Like SimDriveline driveline motion, Simscape mechanical motion occurs in an implicit absolute, inertial reference frame.
